Students often ask us what are the lines in the emission spectrum of the Planeterrella. Each corresponds to a particular excitation, a transition from an excited state to another state. As in a game in a newspaper, we propose you to try identifying yourself For this, Mr. Barthélémy has acquired the spectrum below that you can download: will you identify the lines*?
To compare with the auroral spectrum, you can use the one proposed by NCAR (http://deved.meted.ucar.edu/hao/aurora/txt/x_a_2_1.php)
or one found on http:// / www.aldebaran.cz/actions/2002_aurora/aurora_en.html
